Subnautica 2 Crafting Route Planner

Pick a goal, then open the safest current routes for the materials, tools, vehicles, and biomod systems that support it.

Early Access rule: this planner does not publish final recipe counts unless the current build is verified. It groups known item leads and route guides so you can plan without trusting stale tables.
